On FA world the GDI advantage lasts all the way to the centre but can be offset by using a nod main plus x number of GDI alts, but lets not get into that here :D
I would never dream of trying to play a single nod account on an FA world because I'm not a total masochist. Anyone who sticks a single nod account for a full FA server should get 2 medals imo.
But then take a morale server and its flipped on its head. Unless you have nothing else to do with your entire day than sim OPs then you will choose nod (unless you are really damn good and I am not)
I agree that it would be great to see some more balance between the factions to level out these differences. Likewise with def units, wouldn't it be great if artilleries actually had some useful purpose or any of the other non-infantry cry units.
But we can talk about it all we want, the probability of this amount of reworking of a 10 year old game is next to zero.
